Corrugated Metal Shower

[heimlich]

I am trying to finish my corrugated metal shower. If someone has done this I have some questions.

What did you put behind or around the screws? I figure water will get behind them. We treated the wall with a sealant but I still want to keep the water from getting behind and into the wood.

How about where two seams of metal join? I have the side wall joining with the top. It shouldn't get too wet there but I figure I should put something in it. Can I just inject some silicone in there and fill the gap?

havent done one, but i suspect people use the screws that are used when it goes on a roof. Self tappers with a rubber crush washer. For the corners, i would add galvanized angle flashing under the seams, caulk the seam with Sascho Thru the Roof caulk, and then add another angle flashing over the caulk pressed into it.

For sure don't use silicon caulk, it always fails.

What do you have for a floor drain and pan? The picture is too dark to make it out.

The floor pan needs to have a lip that goes up a couple of inches behind whatever wall material you use.

Honestly, I'd pull out the corrugated material and put in some tub surround (a couple of pieces of white PVC plastic sheeting or equivalent). I don't see how you're going to keep the water out with those kind of seams.

For the basics on using this material, a quick internet search yielded this site: https://bungalowbungahigh.wordpress.com/2010/09/27/galvanized-shower-surround-a-complete-how-to/.

I made my own floorpan out of fiberglass. The fiberglass goes up the wall a bit. The corrugated metal covers it so you can't see it.

hopefully on your pan you made a lip that goes behind the metal walls.. thats the way standard home shower pans are made so that at least at the bottom you dont rely on the bottom caulk to keep water out of the walls

Sure did. It goes about 1/2 to a foot up. That was the easy part. I also put a sealant all over the walls.

Roofing screws with neoprene washers will be a good bet for durability. Shower looks pretty darn good, are you going with a barn wood style interior?

We built the walls and are now trying to finish everything so we can use it. We are just going to paint the wood that we built the walls out of for now. We did a tile countertop. We found some really large 36x36 tiles. For the bathroom we wanted to get it ready to shower in. After we did the countertop we realized we should have just tiled the bathroom but we had already bought the corrugated metal. It's really difficult to work with and you need a lot of strength to bend it around any beams or posts.

Proper planning

Proper planning would include several coats of redguard under the tin, and using proper screw, which have a double washer (rubber with a steel cap) you can either do that (remove the screws you’ve used and replace them with slightly larger sheet roofing screws) or you can caulk the screw heads. But, don’t do that second one. It’ll look like ****, and not last. The corner joints are a different story. There is a proper way to do it, but it’s probably a little late for that. That would have been a bendable bead on the roof section, with the correct “fillers” which are a molded rubber designed to fill those corrugated gaps.

I did the redguard before I put the metal up. I used the Lowe's named brand redguard which comes out turquoise color.

I went back and put some rubber backers on each screw. Before I screws them
in I filled the hole with silicone. Then I put silicone on top of the screw.

I need to get some flash guard and put in the corners. I think that will work well with the corners.


I used these rubber backed washers.

metal shower

our shower is a 32x32 store bought fiberglass shower pan with metal roofing on three sides and a shower curtain. I attached it to the wood lathe with one inch screws that have the metal washer and rubber on it. The corners fit tight enough that I just ran a single small bead of whatever type chaulk/silicone (don't remember) that the metal roofing supply place sold me.
it's been there three years, it's been border to border and coast to coast several times and is holding up well.

In the corners I had bought some very thin aluminum sheet. I also bought some butyl waterproofing tape with a metal cover. I decided to just tape those large seams together using the tape. It works quite well. I put a link below. I also thought about buying the black butyl tape and just stuffing it in there as I did in the windows to stop them leaking.
